Statistic for Frequency Sessions

In the Statistic section of the Statistic tab, you must choose to calculate either frequencies or trends.

Frequencies are counts of records. (In the case of summarized records, such as populations, the counts within the records are actually summed.) Row or column percentages may be calculated with frequencies.

Trends are changes in counts over time. They are expressed in 2 forms: the percent change (PC) and the annual percent change (APC).
